Knuckle Boom Trucks
A knuckle boom, also called an articulating crane, folds like a finger at one or more joints. It tucks compactly behind the cab or at the rear of the bed, leaving deck space for cargo, and its folding reach lets operators place loads precisely over walls or into tight spots. Building supply yards use knuckle booms to deliver roofing and drywall, and landscapers use them for boulders and trees. When buying, compare lifting capacity at full reach, number of extensions, and remote control options. On used units, ask for recent inspection reports and look for leaks at each joint.
